v3+ notes are now extended by [Codex Archive System v3.1 Build Notes](/objects/codex-archive-system-v3-1-build-notes).
Use v3+ as presentation-runtime context and v3.1 for current patch-level operations.

v3+ is the presentation hardening pass layered on top of v3 ingest discipline.

The spine remains stable.
The update is operational, not structural.

Key moves:
- publish `codex-archive-system-v3-plus-notes` as the active release object
- add type-aware share metadata defaults for object pages
- enforce canonical URL emission with production site base (`https://ndcodex.com`)
- introduce a lightweight fallback social card image for objects/pages without media
- refresh favicon set to a minimal codex mark aligned with current visual system
- add clickable fullscreen image inspection on object pages (keyboard + backdrop close)

Learnings now codified:
- share behavior must be deterministic even when object media is absent
- per-type metadata defaults improve consistency across scroll/artifact/fieldlog/signal cards
- image-first objects need direct inspection affordance, not just static media rendering
- default social assets should be explicit and lightweight to avoid crawler ambiguity
- release-note updates should include UI/runtime adjustments in the same operational pass

Adjustments applied:
- object pages now emit canonical, Open Graph, and Twitter tags with type-aware defaults
- fallback social image now resolves to `/social/ndcodex-minimal-og.png`
- artifacts/fieldlogs/nexus continue to prefer large-card previews when applicable
- media-stage and body images can now open into an overlay inspector

No schema expansion is proposed in v3+.
No new object type is proposed in v3+.
